Game of thrones is based on medieval history, especially the war of the roses. For anything bad that happens, worse things happened historically. There is a realism that just isn't present in most fantasy stories, and its dark side is a big part od what makes it so good. As others have said, all the good people have evil qualities and all the evil people have at least 1 good quality.
- Are there any heroes and good guys in the show?
Yes, but for the most part they die quick. Jon Snow, the Onion Knight, Brienne of Tarth, and Beric Donadarrion are about the only ones that last. Tyrion is good and heroic at times, but he frequents whores and has people murdered. But, I think that makes him more heroic than the others. By having the courage to get a little dirty, he actually accomplishes more good than most others.
- Who do you think is kindest and who do you think is the most evil one? Tell your opinion in the comments.
Aside from minor characters, Tyrion is the kindest, and a lot of the suffering he endures is because of that kind streak. Even a lot of what you would call the good guys are fair, but I wouldn't say kind. Varus has a bit of a kind streak. Ramsey is most evil. Joffery is a 2nd, because at least his momma loves him. Also, Ramsey isn't an idiot, so his cruelty is thwarted less.
- Which acts do you think is good and evil in Game of Thrones?
Most of what the starks do is good. Except Arya. Granted she is justified, but assassins are evil by definition. Many of the chivalric knights are good, but that's explored a little more in the books. Much of danys story arc is good, but her body count brings her down to neutral. The church is both, the leaders tend toward evil, but many of the rank and file are good. Evil is too long a list. A lot of it has justification, like Tywin bleeding the riverlands. But there is a lot of rape and murder all over. You'd have to consider the walkers evil, and even my favourite (the dornish) are poison happy killers. But my favorite thing is how all the evil people with a fee exceptions have good qualities. I hated cersei in the books, but I'm a big fan in the show, tywin too, and they're pretty evil. Also you have characters like the hound. He's evil as **** but in his arc he is redeemed. You go from hating him, to respecting him, to loving him.
My favorite character is Ser Bronn of the Blackwater. A lot of his dialog is the same as the book, like "Bronn, if I asked you to kill a child would you do so without question?" "Without question? No. I'd ask how much." Bronn is a survivor. He comes from low birth, and if he was good he would have died long ago. He's one of the best fighters but only goes into fights he can win. Amazingly, despite being a black hearted murderous bastard, he has more honor than most of the Knights in the show. He doesnt live a lie, and he knows exactly who he is and accepts himself for what he is.
Also, I'm one of those book readers, but the show is the best adaptation ever. So many characters I didn't care for in the books that the show made me love. I can't even argue that the books are better in this case, they're just more sprawling. Throw shade all you want, but the show runners did a very good job, and after season 4 or so, it's the only story where show watchers can spoil it for book readers. Also the casting is SPOT ON. Many of the characters are played by the exact actors I pictured before the show came, like Ned n Robert.
I love a song of ice and fire, to the point of obsession. A huge part of that is how there aren't exactly heroes and villains in a traditional sense, just incredibly flawed people. Like how the 'hero of the story' is a mopey bastard that doesn't know anything.
Read the Dunk n Egg stories if you wanna see how far Westeros fell. Good stuff.
